發(fā)布時間:2019-02-28 11:10
【摘要】:以實際水池造流系統(tǒng)為例,采用兩相流瞬態(tài)模擬對水池內(nèi)的速度場進(jìn)行了模擬,并將結(jié)果與單相流的簡化模型進(jìn)行了對比。結(jié)果表明:無滑移壁面和無剪切力壁面兩種方法的模擬結(jié)果較其使用兩相流方法分別小10.8%和5.7%。另外,水池中的流態(tài)發(fā)展將會產(chǎn)生漩渦,并影響出流的角度,而這一過程需要一定時間才能達(dá)到動態(tài)平衡。
[Abstract]:Taking the actual pool flow system as an example, the velocity field in the pool is simulated by the transient simulation of two-phase flow, and the results are compared with the simplified model of the single-phase flow. The results show that the simulation results of non-slip wall and shear-free wall are 10.8% and 5.7% less than those of the two-phase flow method, respectively. In addition, the development of the flow pattern in the pool will produce whirlpool and affect the angle of the outflow, and this process will take a certain time to achieve the dynamic equilibrium.
